Hans Verkuil b32431b753 media: vb2: refactor setting flags and caps, fix missing cap
Several functions implementing VIDIOC_REQBUFS and _CREATE_BUFS all use
almost the same code to fill in the flags and capability fields. Refactor
this into a new vb2_set_flags_and_caps() function that replaces the old
fill_buf_caps() and validate_memory_flags() functions.

This also fixes a bug where vb2_ioctl_create_bufs() would not set the
V4L2_BUF_CAP_SUPPORTS_MAX_NUM_BUFFERS cap and also not fill in the
max_num_buffers field.

Fixes: d055a76c00 ("media: core: Report the maximum possible number of buffers for the queue")
